Description
Technical field
Embodiment described herein is related to portable electric energy memory device, such as electrical equipment (such as vehicle) and
Portable electric energy memory device in consumption electronic product, and it is related to the thermal runaway for this portable electric energy memory device
Relieving system.
Background technique
The battery of known such as lithium ion battery is by more energy in smaller, lighter unit.Lithium ion battery exists
It is widely used for portable electronic device power supply aspect, the portable electronic device is such as mobile phone, plate meter
Calculation machine, laptop computer, electric power tool and other high current equipment.Light weight and high-energy density also make lithium ion battery
For in mixed motor-car and all-electric vehicle using being attractive.
The latent defect of lithium ion battery is its electrolyte solution.In other kinds of battery, electrolyte be by acid or
The aqueous solution composition of alkali, different, the electrolyte in lithium ionic cell unit (cell) is typically by organic solvent
In lithium salts composition, organic solvent is such as ethylene carbonate and methyl ethyl carbonate (can be inflammable).
Under normal operation, it is charged to lithium ion battery so that the lithium ion in electrolyte solution is worn from cathodic migration
It excessively thin porous polymer partition and is inserted into anode.Charge balance electronics is also moved to anode, but it passes through in charger
External circuit.Upon discharging, then inverse process occurs, and electronics flows through powered equipment.
In the case where very rare, it may occur however that the internal or external short circuit of lithium ion battery.E.g., including lithium ion
The electrical equipment of battery may undergo serious impact or shock, cause cell damage, this can lead to short circuit.Due to polymer every
The thin property of plate, the micron-sized metallic particle generated in cutting, compression, grinding or other battery fabrication steps may be present in
In battery cell or it can find into the path in battery cell.These small metallic particles can accumulate and most end form
At the short circuit between anode and cathode.This short circuit must be avoided, because its caused temperature can make cathode and electrolyte solution
It reacts and decomposes electrolyte solution, generate heat and reaction gas, such as hydrocarbon.Typically, in normal operating
At a temperature of, lithium ion battery is highly stable；However, lithium ion battery stability then becomes less on specific temperature
It is easy prediction, and at raised temperature, the intracorporal chemical reaction of battery case can generate gas, causes battery case intracorporal interior
Pressure increases.These gases can discharge more heat and generate in battery or near battery and be enough further with cathode reaction
The temperature of electrolyte is lighted in the presence of oxygen.When electrolyte burning, a small amount of oxygen are generated, this can add combustion-supporting burning.?
The pressure at a certain moment, battery case cylinder accumulation causes cell casing rupture.The gas to shed can be lighted and be burnt.Some batteries
Manufacturer devises battery unit, in the small probability event that battery unit ruptures and lights, supports the gas of burning predetermined
Position and direction shed battery unit.For example, the battery cell with common AAA or AA battery unit shape can be designed
To be discharged from the terminal ends (terminal end) respectively held positioned at battery unit.
In the application that single lithium ion battery is used only, a possibility that failure and burning of battery, can generate undesirable
Situation.When multiple lithium ion batteries are deployed as the form of battery pack or module, the seriousness of such case be will increase.?
There may be the offices higher than making the temperature of other lithium ion battery normal tables for the burning occurred when one lithium ion battery failure
Portion's temperature causes these other battery failures, rupture and then ignited and burnt gas is discharged.Therefore, lithium-ion electric
The rupture of single battery unit may cause the rupture of other battery units in the group in cell stack and discharge is lighted and burnt
Gas.Fortunately it has been confirmed that lithium ion battery is very safe, and the failure of lithium ion battery ruptures right and wrong with caused by
It is often rare.Nevertheless, people are also directed to reduce rupture and light the gas flowed out from rupture lithium ion battery
Risk.For example, the development of the material for cathode has generated the cathode material based on lithium, this is than widely used lithium cobalt oxidation
Cathode made by object is more heat-resisting.Although these materials developed recently are more heat-resisting, this has cost.For example, phase
Than in lithium and cobalt oxides, lithium manganese oxide cathode has lower charge capacity, and still can decompose at high temperature.Lithium phosphate
Iron cathode is especially resistant to heat injury (thermal abuse)；However, compared with lithium and cobalt oxides cathode, based on capacity
Operating voltage and energy density are lower.
Other work are dedicated in polymeric separator plates and its design.It has been proposed, for example, that using two layers of polypropylene by one layer
The polymeric separator plates that polyethylene is clipped in the middle are directed to the degree of protection that slightly overheats to provide.When the temperature of battery unit starts to connect
When the temperature of nearly unpredictable battery unit stability, polyethylene is melted and is filled in polyacrylic hole.Work as vinyl stopper
When entering polyacrylic hole, lithium diffusion is stopped, to effectively shut down battery unit before the fuel cell that has an opportunity.
Other work, which efforts be made so that, is higher than polyacrylic polymeric separator plates with fusing point.It has for instance been proposed that formed by polyimide
Partition and the partition formed by the ceramic layer of High molecular weight polyethylene and insertion, to form more robust high-melting-point polymer
Partition.Allotment is investigated to use less flammable electrolyte and non-volatile, non-flammable ionic liquid, fluorine ether
(fluoroether) and other high fluorated solvents are as cell electrolyte.Researcher has developed without liquid
Lithium ion battery.These solid state batteries include inorganic lithium ion conductor, are substantially non-flammable thus highly stable, peaces
Entirely, and there is long life cycle and shelf life.However, the manufacturing cost of these solid state batteries is very high, and need high labor
Move intensive vacuum deposition method.
Although above-mentioned work has been carried out, there is still a need for a kind of portable electric energy memory device, the device can be effective
Ground manages following risk: electric energy storage batteries cell failure and in the deployment of more battery units because of failure caused by gas combustion
It burns and the propagation of failure introduces thermal energy to the battery cell adjacent with faulty battery cell, and is this rare in generation
Harm is generated to user when seeing event.

As described in " background technique ", in the application that single electric energy storage batteries unit is used only, the burning of battery unit
Undesirable situation can be generated.When multiple electric energy storage batteries units are deployed to the form of battery pack or module, this can be aggravated
The seriousness of kind situation.For example, when electric energy storage batteries unit includes lithium ion chemical composition, the combustion of lithium ion chemical composition
It burns and can produce the local temperature for being higher than and making unstable, rupture and burning the temperature of lithium ionic cell unit.Therefore, lithium ion battery
The burning of single lithium ionic cell unit in group may cause described group of rupture, light and burn.Fortunately it has been confirmed that lithium from
Sub- battery unit is very safe, and the rupture of lithium ionic cell unit and burning are very rare.However, for the peace of user
Full interests and use electric energy storage batteries unit as the acceptance of electric vehicle power supply, take action to reduction generation lithium from
A possibility that rupture and burning of sub- electric energy storage batteries unit and the thing being unlikely to occur lighted in this battery unit
Management burning is very important in part.
According to embodiment as described herein, electric energy storage batteries list is managed by the combination of following characteristics as described herein
The burning of member or the burning of multiple electric energy storage batteries units.Firstly, using since rupturing battery unit gas ignition with
The burning of support level fuel cell unit needs oxygen.Secondly, limitation thermal energy from failure and may fire in the event burnt
The battery unit of burning is migrated to other battery units.Third burns gas caused by battery unit failure and this gas
Gas control is formed by airtight electric energy storing device, up to specific threshold pressure.4th, control electric energy accumulator

Firstly, lithium-ion electric energy storage batteries unit is contained in the air-tight casing of no oxygen, by battery unit and incite somebody to action
Oxygen isolation required for being lighted from the combustible gas that cracking battery unit is discharged and it is maintained to burn.Therefore, exist
Single battery cell failure causes battery unit to rupture and lights the unlikely scenario of the gas being discharged from battery unit
In, oxygen that the reaction occurred between the reactant that can be used for maintaining the oxygen of burning to be limited by faulty battery cell generates
Gas.The oxygen that can support burning is limited to the oxygen that (in situ) is generated in situ, so that electric energy storing device burns
Time span it is most short, thus reduce that temperature in device is increased to break down and subsequent rupture and burning are from other electricity
A possibility that gas of pool unit.In addition, no oxygen can prevent the burning of thermal energy absorbing material in electric energy storing device.For example,
Phase-change material as thermal energy absorbing material is flammable when becoming liquid.Contained by limiting oxygen in electric energy storing device
Amount, avoids the burning of phase-change material.
Typically, the gas discharge from independent electric energy storage batteries unit and burning only maintain the several seconds.In this time
In, local temperature is close to so that adjacent electric energy storage batteries unit becomes unstable temperature.In order to which other are stable
Electric energy storage batteries unit is isolated with the thermal energy being discharged from faulty battery cell, occupies adjacent electricity by above-mentioned thermal energy absorbing material
Gap between energy storage batteries unit.What thermal energy absorbing material absorption was discharged by battery unit failure and from faulty battery cell
Thermal energy caused by gas burns, the temperature without increasing thermal energy absorbing material.Thermal energy absorbing material in electric energy storing device exists
The amount of absorbable thermal energy depends on the composition of thermal energy absorbing material and the current volume of material before its temperature is begun to ramp up.Example
Such as, the volume of thermal energy absorbing material is enough to absorb the failure by certain amount of battery unit and the complete of the thermal energy generated that burn
Portion；However, thermal energy absorbing material can not be absorbed in the case where not increasing temperature if other battery unit failures and burnt
Additional thermal energy.
In the event being unlikely to occur, it is more than that thermal energy absorbing material can inhale that failure electric energy storage batteries unit, which generates,
The increase of a possibility that thermal energy of the amount of the thermal energy of receipts, other electric energy storage batteries units may break down and burn causes certainly
The Potential feasibility of body fault propagation and the burning of other battery units.When not including feature disclosed in the present application, this itself

The quantity of pool unit is less than predetermined quantity, then the pressure increase in shell 16, which will not generate, makes shell 16 that uncontrolled explosion occur
Significant risk.On the other hand, if the quantity for the electric energy storage batteries unit lighted and burnt is greater than predetermined quantity, shell
Interior pressure increase will increase the risk of the uncontrolled explosion of shell.Explosion structure 30 is designed to the pressure in shell 16 and reaches pre-
